Remember, to unlock this mission you must play (or replay) any two Extra Ops missions after beating Mission 26. When you do this, Zadornov will escape to the jungle in El Cenagal. He'll appear in one of several places (usually in the Bananal Fruta de Oro map in our experience). The other places will always have a Prisoner, so be sure to check them out as well! When you find Zadornov he'll be crouching in a corner. Simply grab him and choke him once. Use the Fulton Recovery System to extract him (save some of your Fulton rounds for this!).

Rio del Jade

The first place you should head is to the east of your starting point in El Cenegal: Jungle. Take the eastern exit and you'll find yourself in the Rio del Jade area.

There are two structures here you need to search. First anesthetize all four soldiers in the area with the Mk. 22. Now, search the small southern building for a Prisoner OR Zadornov. If he's not there, move northeast to the boathouse. A ladder in leads to the upper level. Up here is a Prisoner or Zadornov.

Now, move on to the Bananal Fruta de Oro: Sorting Shed using the northern exit. You'll pass through the Swamp and Ravine areas which each have several enemies. With your Sneaking Suit and Mk. 22 you shouldn't have a problem.

Bananal Fruta de Oro: Sorting Shed

Search the small room on the western side of the area for a Prisoner or Zadornov. Sneak past the few guards to the far north.

Search the northern room and you'll find Zadornov if you haven't yet. The exit appears here as well. Extract Zadornov with the Fulton and head outside the small room to find the exit marker.

Before leaving, you may want to head to the south portion of the El Cenegal: Swamp area and collect the Smoke Grenade (Colored) Design Specs. This worthless item is waiting for you across the level if you want it.

You'll have to do an additional two Extra Ops missions before Zadornov escapes again...
